Hi,
When converting from lines to raster using v.to.rast, the result is good when still a temporary file, but when i saved it, the lines are know disconnected:
Temporary file:
Saved geotif file:
How to solve?
OBS: v.to.raster: https://grass.osgeo.org/grass78/manuals/v.to.rast.html

… what are your steps in detail?
v.to.rast generates directly a raster map, which temporary file do you refer to?
And when you export this raster map to e.g. GeoTIFF with r.out.gdal, it is done at the resolution and extent of the computational region.
Pseudo-code
g.region … set to desired raster resolution and extent (bounding box)
v.to.rast …
r.out.gdal …
Best,

My fault => forgot to write that the process was done in GRASS GIS, from QGIS. The temporary file is loaded by default and then i save it (geotiff) in some location. Does it make sense?
I’am using QGIS 3.12.0 + GRASS 7.8.2
